## Create the instance

1. Open the Modrinth App and click **Create** (the **+**) in the left bar.
2. Give it a name, and pick the **loader** (Fabric, Quilt, Forge or NeoForge) and the **Minecraft version**.
3. Click **Create**.

## Add mods

1. Open the instance and click **Add content**.
2. Search for each mod and click **Install**. The app only shows mods for your loader and version, and adds required mods for you.

Launch it once to check it loads.

## Share it

Open the instance's **⋮** menu and choose **Export modpack**. This makes an `.mrpack` file your friends can open in the Modrinth App, or in Prism Launcher via **Import**.

## Run it on your Beacon server

1. In **Package Manager**, install the **same loader and version** as your instance.
2. Install each server-side mod from **Package Manager** (**Browse packages**, search, **Install**). Leave out client-only mods such as minimaps, shaders and HUDs.
3. Restart the server from **Console**.

If you publish your pack on Modrinth, you can install the whole thing on the server from **Package Manager** like any other modpack.
